20120114595 | SUGAR CHAIN-ADDED AILIM EXTRACELLULAR DOMAIN AND METHOD FOR PRODUCING SAME - Disclosed is a synthetic AILIM extracellular domain which has high ligand-binding ability and a quality sufficient for a pharmaceutical product. Also disclosed is a method for synthesizing the synthetic AILIM extracellular domain. Specifically disclosed is a sugar chaim-added AILIM extracellular domain wherein a sugar chain is bound at a position corresponding to the 69-position of the amino acid sequence of human AILIM extracellular domain, said amino acid sequence being depicted in SEQ ID NO: 7, and no sugar chain is added at positions corresponding to the 3-position and the 90-position of the amino acid sequence. | 05-10-2012 |
20120264684 | Glycosylated Form of Antigenic GLP-1 Analogue - Disclosed is a glucagon-like peptide-1 (GLP-1) analogue which is obtained by ameliorating a highly antigenic GLP-1 analogue so that the GLP-1 analogue has reduced antigenicity without being lowered in the blood glucose suppressing activity. Specifically disclosed is a glycosylated form of an antigenic GLP-1 analogue, which has GLP-1 activity and is obtained by substituting at least one amino acid of an antigenic GLP-1 analogue with a glycosylated amino acid. | 10-18-2012 |
